JaguarDrive Control Sub-System Faults
If a fault occurs in a sub-system, the driver is alerted by the illumination of a warning indicator and/or an appropriate message
for that sub-system in the instrument cluster message center. No JaguarDrive Control message will be shown when a failed
sub-system displays its own message.

When a sub-system fault is present and the driver attempts to select a different JaguarDrive Control mode or at the next
ignition on cycle, a message 'WINTER MODE FAULT' or 'DYNAMIC MODE FAULT' will appear in the message center. This
generally implies that the JaguarDrive Control system has a fault, but only because a sub-system fault is preventing its
operation. This message will be displayed once per ignition cycle, but is repeated if a further selection is made by the driver
using the JaguarDrive Control buttons or at the next ignition on cycle.


NOTE: The message 'WINTER MODE FAULT' or 'DYNAMIC MODE FAULT' can also in very rare circumstances be generated
by a fault in the JaguarDrive Control module.

It is not possible for the JaguarDrive Control module to cause any fault behavior (warning indicator illumination or message
generation) in any of the sub-systems. Illumination of a sub-system warning indicator and/or a sub-system related message
will never be associated with a JaguarDrive Control module or JaguarDrive Control system fault.

The sub-system control modules can detect a fault with the CAN (controller area network) bus signal from the transmission
selector module. If a fault in the JaguarDrive Control system is detected, the sub-system control modules will operate in the
'special modes off' setting. The sub-system control modules will record a fault code for a failure of the JaguarDrive Control CAN signal. These faults can be retrieved using the Jaguar approved diagnostic tool and will provide useful information to indicate
investigation of the JaguarDrive Selector module or the CAN bus network. JaguarDrive Control System or Control Module Fault

If a fault occurs in the JaguarDrive Control system, all button icon LED (light emitting diode)'s will be turned off (background
illumination will remain on) and pressing of the JaguarDrive Control buttons is ignored. The instrument cluster message center
will display a message 'WINTER MODE FAULT' or 'DYNAMIC MODE FAULT' when the fault occurs, if the fault is present and the
driver attempts to select a special mode (if the control module is able to do this) or at the next ignition on cycle.

The JaguarDrive Control buttons and control module (JaguarDrive Selector module) are an integral unit. If a fault occurs in
either component, the whole unit will require replacement, however, this is extremely unlikely.
CAN Bus Faults

If a CAN bus fault exists and prevents JaguarDrive Control system operation, all of the JaguarDrive Control button icon LED's will be illuminated and rotation pressing of the JaguarDrive Control buttons is ignored.

If the instrument cluster does not receive a JaguarDrive Control system CAN bus message from the JaguarDrive Control module, the message 'SPECIAL MODE UNAVAILABLE' will be displayed when the fault occurs and will be repeated at every
ignition on cycle.
User Error

A special mode change while DSC or ABS is active (this includes ABS cycling) may be misinterpreted as a system fault.

JAGUARDRIVE CONTROL DESCRIPTION Component Description



Item Description 1 Winter mode button 2 DSC/TracDSC mode button 3 ASL (automatic speed limiter) - Reference only, not part of JaguarDrive system 4 Dynamic mode (Supercharged models only) The system is controlled by buttons adjacent to the JaguarDrive Selector located on the floor console. The buttons allow the
selection of one of the following 3 modes:

Special modes off
Winter mode
Dynamic mode (Supercharged models only).
The instrument cluster will display the selected JaguarDrive Control mode in the message center.

The JaguarDrive Control system uses a combination of a number of vehicle sub-systems to achieve the required vehicle
characteristics for the mode selected. The following sub-systems make up the JaguarDrive Control system:

The Engine Management System (EMS)
Automatic transmission
Brake system.

The JaguarDrive Control software is stored in the JaguarDrive Selector module located below the JaguarDrive selector. The
module detects the selection made using the buttons and transmits a signal on the high speed CAN bus, which is received by each of the sub-system control modules.

Each of the affected sub-system control modules contain software, which applies the correct operating parameters to their
controlled system for the JaguarDrive Control mode selection made.

Each sub-system control module also provides a feedback for the selected mode so that the JaguarDrive Control software can
check that all systems have changed to the correct operating parameters.


NOTE: The JaguarDrive Control system is a co-ordinating system only. It CANNOT generate a fault in one of the
participating sub-systems. All participating sub-systems should be FULLY diagnosed before assuming a fault with JaguarDrive
Control. Replacing the JaguarDrive Selector module should not be done until all other options have been exhausted. JAGUARDRIVE CONTROLS

Winter Mode



To activate winter mode, press the winter mode button briefly (not less than 300 ms) to activate or de-activate the mode.


NOTE: Winter mode cannot be active at the same time as dynamic mode (Supercharged models only).

When active the winter mode icon and message appear in the instrument cluster message center to confirm the activation.
Dynamic Stability Control (DSC)



Press the DSC mode button briefly (not less than 300 ms) to switch between DSC and TracDSC. The instrument cluster
message center will display either 'DSC ON' or 'TRAC DSC' depending on which selection is made. When TracDSC is selected,
the DSC warning lamp in the instrument cluster is illuminated and the DSC button is illuminated.

DSC can be manually switched off by pressing the DSC mode button for more than 10 seconds. Confirmation is given by a
chime from the instrument cluster, 'DSC OFF' is displayed in the instrument cluster message center and the DSC warning lamp
in the instrument cluster is illuminated.


NOTE: DSC is operational at all times when the engine is running unless manually switched off.

Dynamic Mode (Supercharged models only)



To activate Dynamic mode, press the button briefly. The dynamic mode and DSC buttons are illuminated. 'Dynamic Mode
Confirmed' message is displayed in the instrument cluster message center and the DSC off warning lamp in the instrument
cluster is illuminated (due to automatic selection of TracDSC in Dynamic mode).


NOTE: Dynamic mode cannot be active at the same time as winter mode.

Once activated, TracDSC is automatically selected. In gearbox Sport mode, the driver has full control over the transmission
shift points and the TCM will not intervene to prevent engine overspeed (for example; upshifts are inhibited in gearbox sport mode when Dynamic mode is selected). In this setting, the gear indicator in the instrument cluster will turn amber at high
rev's to indicate an appropriate manual upshift point.

STEERING COLUMN ADJUSTMENT SWITCH

The column adjustment switch is located in the steering column lower shroud and held in place with a spring clip. The switch
allows the adjustment of the steering column for both reach and rake angle. The switch has an auto position which allows the
desired position of the column to be set by the driver using the driver's seat memory buttons. The column position is Item Description 1 Auto/intermittent rotary switch 2 Fast wipe 3 Slow wipe 4 Intermittent wipe 5 Off position 6 Wash/wipe 7 Flick wipe www.JagDocs.com

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
